HARDIVICKE'S SCIENCE-GOSSIP.

towed up and down. The long steamers of the 

 present day could not turn. A brief account was 

 also given of the great changes which have occurred 

 on the coast of Suffolk. Here the great and famous 

 City of Duhwich, the seat of St. Felix, the first 

 Christian Bishop of East Anglia, has been almost 

 entirely destroyed, not as at Sandwich by the accu- 

 mulation of deposits, but by the inroad of the sea. 

 This has carried away not only the once famous 

 harbour, but almost the whole site of the town, 

 leaving one solitary ruined church as a survivor of 

 forty-eight. In conclusion, the lecturer contended 

 that this border land between geology and history 

 was a most interesting subject for study, not only in 

 relation to the probable antiquity of the present 

 configuration of our coast, but also as throwing light 

 on most important historical events in early times. 



NOTES AND QUERIES. 



A Strange Wasp's Nest.— During the month of 

 October, I had a very complete wasp's nest given to 

 me ; it was not very large, but the curious part was, 

 that the leg of a small bird was projecting horizontally 

 from one side. The question is how it got there, and 

 how the wasps were able to build their nest com- 

 pletely round it, whilst it was in a horizontal position ? 

 The bird is, I believe, a wren. Can any readers of 

 Science-Gossip explain it or cite similar occurrences ? 

 — C. F. George. 



Early Catkins.— As I think it is very unusual 

 to find at this time of year catkins on the hazel, I 

 enclose a specimen gathered at Wargrave-on-Thames 

 this week. — Addison Crofton. 



Castor. — Is your contributor correct in applying 

 (Curiosities of Drugging, Science-Gossip for Nov.) 

 the term "Castor," to a highly odorous secretion 

 peculiar to the male of the musk-deer of Africa ? I 

 have always understood that it was peculiar to the 

 beaver {Castor Fiber). — Moyhitt. 



NOTICES TO CORRESPONDENTS. 



To Correspondents and Exchangers. — As we now 

 publish Science-Gossip earlier than formerly, we cannot un- 

 dertake to insert in the following number any communications 

 which reach us later than the 8th of the previous month. 



To Anonymous Querists.— We must adhere to our rule of 

 notnoticing queries which do not bear the writers' names. 



To Dealers and Others.— We are always glad to treat 

 dealers in natural history objects on the same fair and general 

 ground as amateurs, in so far as the "exchanges" offered are fair 

 exchanges. But it is evident that, when their offers are simply 

 disguised advertisements, for the purpose of evading the cost of 

 advertising, an advantage is taken of o\ix gratuitous insertion of 

 " exchanges " which cannot be tolerated. 



We request that all exchanges may be signed with name (or 

 initials) and full address at the end. 



Pulex.— Kindly send us one of your proposed papers to look 

 over. 



Alg^e. — There is no cheap work on freshwater alga;. You 

 will find much relating to them in Dr. Cooke's "Ponds and 

 Ditches." Dr. Ha-sall's " Freshwater AUae," 2 vols., may 

 somewhere be got secondhand of the scientific booksellers. In 

 the earlier volumes of Science-Gossip you will find many illus- 

 trations and sketches of Desmids and allied forms. 



Miss Layard. — Your reply on "Rudiments and Vestiges " 

 reached us too late for insertion this month. 



S. A. H.— Get Rye's "British Beetles." There is also a
